Osiris was interesting to design as there were so many different directions you can take for this character. I lost my thumbnails, so unfortunately I can only show the final design. Drawing ellipses in perspective has always been an issue for me. For the anklet behind Osiris, I had to seek the aid of 3DSMax to provide a reference.
